Now you can (officially) unlock bootloaders on the HTC Evo 3D and Sensation

HTC has followed through on its promise to let users unlock the bootloaders of its most recent Android smartphones. Earlier this month the company launched a web-based tool that you could use to unlock the Evo 3D bootloader as well as the European version of the HTC Sensation.

Now we can add the Sensation 4G on T-Mobile in the US as well as Turkish, Arabic, and Bouygues Telecom versions of the phone.

Unlocking the bootloader makes it possible to replace your phone’s firmware with custom ROMs that may offer special features not available in the software that comes with the device. But while HTC is making it easier to unlock a device, the company doesn’t plan to offer support for unlocked phones. If you use the free service to unlock your bootloader you will void your phone’s warranty.
